As it happened: US presidential debate - Trump vs Clinton

Mr Trump did his best to remain calm and measured but that didn't last long. He often repeated himself and didn't appear to have a plan for anything accept cutting taxes.

Ms Clinton had a solid debate. One of the most memorable things she said was "just listen to him". That comment got a few laughs. She talked up her record in foreign policy, saying she stopped Iran's nuclear ambitions without a shot being fired.

Plenty of shots were fired in this debate, but Mr Trump appeared to shoot himself in the foot when he stated he didn't know much about NATO.

Ms Clinton easily claimed the points in this first of three debates. It will be very interesting to see how Mr Trump approaches the second. Will he have more answers?

All he appeared to produce tonight was more of his hate-filled rhetoric, but in a slightly calmer and less manic approach.

The final word has to go to Jerry Springer:

3:34 Another personal attack from Mr Trump: Hillary doesn't have the stamina to be a US president. (That's nasty given her recent health woes)

3:33 Mr Trump wants US allies to pay more for the right to be protected by the US.

3:30 Ms Clinton: Wants to assure US allies "our word is good". Warns Mr Trump would start wars. (Some not so subtle sub-text there: would you want his finger on the nuclear trigger?)

3:29 Mr Trump playing the fear card "we're not keeping up with Russia's nuclear build up". Accuses China of not doing enough to stop North Korea's nuclear ambitions.
